A new PMOS backgate quadrature voltage controlled oscillator (QVCO) is designed and implemented using TSMC 0.18 mu m 1P6M CMOS technology. The phase noise of the PMOS hack-gate coupled QVCO operating at 1.5 V is measured to be -100 dBc/Hz and -125.08 dBc/Hz at 100 KHz and 1 MHz offset, respectively, for a low power consumption of 15 mW. The backgate QVCO demonstrates a wide frequency tuning range, a low phase noise, and a low power consumption. The corresponding figure-of-merit of the QVCO is -186 dBc/Hz.
